bad VR issue, Rift S

[30mikemike]

Still no joy unfortunately. Ran the DDU uninstaller on the GPU drivers, re-loaded the drivers but still the same. One thing worth mentioning is ever since I got my new PC I've noticed the graphics card is quite noisy, almost like a high pitched buzz when under load. I believe this is normal but when I load DCS and it starts to stutter this buzz stops and that's when I get the freezes. Thought it might be a power issue on the Rift but swapping the USB's about made no difference. Really am struggling now!

And in 2D you don't have that?

Can you make a sound recording of that buzz, stops included?

In 2D the buzzing sound is very, very faint and the performance is perfect. Ultra smooth on high settings. I was under the impression the buzzing sound is just the normal coil whine that we can get with cards such as mine but I'm not 100% sure.

Something else i tried last night was a GPU stress test. I ramped the settings up to the highest they could go and set it to run, the benchmarking results were excellent (FPS etc) but this buzzing sound was really noticeable and in places it was stuttering, exactly like it does in VR in DCS, same buzzing sound and then stuttering, even though the FPS was still high, something like 170 ish. Temps were fine, never went above 50 degrees but I do have an expensive GPU & CPU liquid cooling setup to be fair. Strange indeed this is! :doh:

[Svsmokey]

Liquid-cooled gpu -overclocked ? Maybe back off the overclock a bit ?

Yeah it's liquid cooled and it's the Strix overclocked 1080Ti. Although I've never altered the clock on it, it's been the same since I've had it.

Yeah I’ll do a recording later tonight....

[30mikemike]

So stupidly installed this afternoons latest beta, needless to say my issues are worse. Oh and I tried the X-Plane 11 demo too, same story there.

I even uninstalled the 3 recent Windows 10 updates back to the one in April when I know things were spot on. Still the same.

[30mikemike]

Another weird one to add to my issues...the performance of the latest beta when running on my monitor is outstanding. Seriously amazing. But, plug the Rift in and it cripples it! WTF?? :mad:

[Taz1004]

Both the monitor and VR plugged into your graphic card and not onboard graphics? Just a thought.

 

High FPS but stutter is symptom of Legacy Reprojection Mode in Steam VR. I'm not sure if Oculus have similar feature. I uninstalled Oculus a while ago.

 

After everything that was suggested, I say it's time to reinstall Windows. It only takes couple hours thesedays.

Yeah both VR & monitor plugged into the card. The only feature in Oculus is the ASW mode. I have it set to auto so if it can’t hit 80 then it goes to 40fps and that’s where ASW comes in. Tried all different modes of it too, no joy.

Yep, my mate text me earlier and said maybe time to reinstall Windows so looks like I’ll be doing that. Not a massive issue because there’s nothing on the PC apart from DCS.

Fingers crossed that’ll sort it.

[30mikemike]

So after plugging my mates Rift S in and going through the setup on that in Oculus, it appears to have fixed the issue. God knows how that fixed it but it did! Weird indeed.

[30mikemike]

I spoke too soon - Doing it again tonight, quite badly. Was absolutely fine yesterday. Sound in my headphones dropping out when it stutters too. FFS.....:mad:

 

I’m going to delete the entire DCS from my PC and reinstall. It was playing up big time tonight on a Nevada flight so I stopped that, jumped straight into another flight on Nevada that I was on yesterday and it was absolutely fine. Both in the F-16. I’m beginning to think this is a problem with the game rather than my Rift or GPU etc...

 

How do I completely remove all trace? Just simply delete all folders on both the C: & D:?

Its not DCS causing the issue. Its Oculus. It wont get better until they fix it.

But the last Oculus update was somewhere round the 20th April and it's been fine up until about two weeks ago. I'm not convinced it's Oculus.

Yeah I kind of doubt it unless one somehow has a corrupted Oculus install.

Should be easy to check in other games.

Oculus working great on my end.

It’s just weird how it does it sometimes and then not others. Firstly I’ll completely reinstall DCS and if that doesn’t work then a reinstall of Windows. If that doesn’t work then it’s hardware or back to TrackIR.

Haven't read all through this thread, but stutters in VR sound like the hot plugging issue? Has someone already suggested that. I had this just start occurring randomly. Tried everything and it was really bad. In the end the hotplug fix (script file I added to my DCS folders) fixed it 100%. https://forums.eagle.ru/showthread.php?t=251377

I'm pretty sure I've got this already set. It definitely says this in my log. Unless I've not done this correctly?

"Device hotplug disabled!".

 

 

Do you have to do this after any updates or roll back of Beta etc or does it stay all the time?

I must admit it certainly seems like I'm having this issue but unless I've not installed it correctly then it doesn't work for the issue I'm having.

Ah ok shame. I went through loads looking for the fix of my stutters, and this was the magic bullet. Maybe check you have the file stated, but does sound like something else.

I'll double check again tonight. Maybe worth one of the technical guys to look at a DCS log after it's been playing up? BigNewy? Help please before my PC takes a trip out the window! :helpsmilie:

[Flyingfish]

I haven't read the whole thread but have you tried disconnecting your computer from the internet? I had a similar problem a few months ago where I had stutters on DCS and elite dangerous but no other games. Turned out it was a hard drive connected to my router which was causing the problem.

[30mikemike]

Right, this is going to sound ridiculous but...………

 

Say my hand controller batteries were low, could this cause issues in the Rift?

 

I had problems with the Rift connecting too but I've just changed the batteries in the hand controllers and it seems to be fine now. Connects fine and more importantly it appears there's no horrible lags and stutters....:huh:

[Hoirtel]

Usually mine is fine before it abruptly interupts me and tells me a battery is low but who knows. Could be.

Well that was short lived, 2 flights and all was fine. Closed the PC down for a bit, back on a min ago, same mission, complete stutter fest. FFS.

Something really odd is going on, with your rig that should certainly not be the case.

Going to be hard to pinpoint.
